Patent DE-3000826-A1 (DE)
Title: Dish washer - circulating cold water with added emulsifier, bromide soln. and ozone
IPC: C11D7/10
Filed: 1980-01-11
Abstract: Dish washing system for domestic and commercial purposes is based on an enclosed chamber through which the wash liquid is circulated without any heat input. The liquid is doped with an emulsifier and with aqueous hydrobromic acid or bromide soln. and with ozone. A redox sensor automatically maintains the wash water quality. Recycled water is thus always clean and not increasingly laden with food remnants. The water remains cold and the power required for hot water is aved. Effective cleaning is achieved with a short cycle time.

Patent DE-3103684-A1 (DE)
Title: Oil burner
Inventor: SCHILLING JUERGEN DIPL ING
IPC: F23D11/24
Filed: 1981-01-31
Abstract: The present invention relates to an oil burner with a fuel-supply line which is fed from a pump via a shut-off valve and at the burner-side end of which a nozzle is arranged. Such oil burners are regularly stopped by making the pump currentless and by closing the shut-off valve, usually a solenoid valve. However, the heat of the combustion space subsequently acts on the oil-supply line from the shut-off valve to the nozzle, and the fuel still located here expands, fuel consequently dripping into the combustion space. The object on which the present invention is based is to avoid this so-called subsequent dripping, and the object is achieved in that there is arranged between the shut-off valve and the nozzle of the supply line a vacuum generator, to the suction point of which a vacuum space is connected. While the oil burner is operating normally, therefore, a vacuum is built up, and, after the closing of the shut-off valve, leads to oil being sucked back out of the fuel line, so that an expansion of volume as a result of the subsequent heat does not lead to dripping.

Title: Circuit arrangement for disabling keys of a control device for an signal box
Inventor: BOEHM PETER ING GRAD
IPC: B61L21/04
Filed: 1981-04-10
Abstract: The subject matter of the invention is a circuit arrangement for disabling keys of a control device in an signal box in which, in addition to manual control operations, triggering of signal box processes is also performed by means of automatically operating devices (self-signal box mode, number signal box console, computer control, remote control). The deactivation of the keys takes place automatically during the access of the automatic devices and safeguards the automatic signal box mode against faults resulting from simultaneous activations of keys. In order to safeguard the signal box console against being operated by unauthorised persons, the deactivation of the keys can also be performed by the operator for example by means of a breaker mechanism, the automatic signal box mode continuing undisturbed.

Title: Safety device for containers and conveying systems
Inventor: ISLIKER ALWIN
IPC: B65D90/32
Filed: 1981-06-26
Abstract: The safety device is inserted into the conveying line between a tanker and a container or between two containers, and comprises a shut-off device (6), a pressure sensor (5) inserted in the container and acted upon by the delivery flow and a sieve (7) for protecting the shut-off device against foreign bodies. The shut-off device has a closing flap (8) which is constantly held in its closed position by a spring (12). During the filling process, the closing flap (8) can be held in the open position by an electromagnet (15). When a critical pressure occurs (which is established by the sensor (5)), the feed of current to the electromagnet (15) is interrupted and, as a result, the spring (12) brings the closing flap (8) into its blocking position. <IMAGE>

Title: Closing device for coin cassettes
Inventor: LUDWIG MAX
IPC: G07F9/06
Filed: 1981-08-28
Abstract: The invention relates to a closing device for exchangeable coin cassettes in coin-operated machines, a coin-insertion slot (14) arranged in the lid (4) opening automatically when the coin cassette is pushed into a mounting (16), and closing automatically when the cassette is pulled out of the mounting. The object of the invention is to allow a reliable locking and unlocking of the coin cassette. The object is achieved in that the closing device is arranged in the lid (4) of the coin cassette and has a closing plate (12) which is mounted rotatably and which controls a disc (19) guided in a slotted link, in such a way that, once the coin-insertion slot (14) is in a closed state, a curved path of the locking element (3) bears on an extension of the disc (19) and the extension of the disc (19) bears on a curved path (17) of the closing plate (12), so that, if an object is improperly pushed in instead of the mounting, the closing device jams and the coin-insertion slot is prevented from opening. <IMAGE>

IPC: B62D15/00
Filed: 1981-09-08
Abstract: A method and a device for steering vehicles with rigidly coupled wheels and separate drive for each side of the vehicle is proposed. The driving signal is logically connected in a multiplier to a steering signal. If a steering lock takes place, the product of steering signal and driving signal is added to or subtracted from the driving signal. By means of the evaluation circuit it is ensured that when going round a bend the drive on the outside of the bend is not influenced whilst the drive on the inside of the bend receives a weakened or reversed signal. Using these output signals, a power control for operating the drive motors is actuated. <IMAGE>
